The clinical significance of fluid collections in acute pancreatitis.
Computed tomography (CT) displays fluid collections in patients with acute pancreatitis as well defined intra- or extrapancreatic homogeneous areas with low attenuation numbers. We followed, prospectively, the clinical courses of 128 patients who had CT during an episode of acute pancreatitis, to determine the natural history and clinical significance of any fluid collections that developed. Fluid collections were found in 48 (37%) of the 128 patients with pancreatitis. ⋯ Of the 25 patients not requiring operation, five were lost to follow-up, and 19 of the 20 who had spontaneous resolution of their fluid collection(s) had collections less than 6 cm in diameter. The eight patients who required operative pancreatic debridement for abscess or necrosis had multiple small fluid collections. In summary, fluid collections were found in one-third of patients with acute pancreatitis and were often associated with the development of local complications.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative StudySurvival after hypertonic saline resuscitation from hemorrhage.
There has been recent increased interest in hypertonic saline resuscitation from shock and hemorrhage. This study was performed to evaluate the survival effects of hypertonic saline resuscitation. Fifty male Sprague-Dawley rats of average weight of 325 grams were anesthetized with halothane. ⋯ Rats were observed 3 days for survival. Survival was significantly lower in the three per cent NaCl group compared with the lactated Ringer's group. It is probable that worsened outcome with three per cent NaCl was associated with intracellular dehydration.

Three cases of postoperative pulmonary lobe torsion were reported. Two of three showed hemorrhagic infarctions, and as a result underwent rethoracotomies and removal of the affected lobes. From these experiences, we consider that computed tomography (CT) and bronchofiberscopic examinations are useful for the diagnosis of advanced torsion.

The charts of 56 consecutive patients with penetrating injuries to the abdominal aorta were reviewed in an attempt to identify prognostic factors. Mechanism of injury was gunshot wound (GSW), 82 per cent (.22 cal: 15.2%; greater than .38 cal: 84.8%); shotgun wound (SGW), 5 per cent; and stab wound (SW), 13 per cent. Overall mortality was 73 per cent, with GSW 78 per cent (.22 cal: 0%; greater than .38 cal: 92%), 67 per cent with SGW, and 43 per cent with SW. ⋯ At surgery, six patients had thoracotomy before celiotomy for control of the thoracic aorta, with three surviving the OR and two surviving long-term. Survivors had 2.53 associated injuries; nonsurvivors had 2.89 (NS). No significant difference was noted in number or location of associated injuries between survivors and nonsurvivors.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgeons have long recognized that a proportion of hospitalized trauma patients present with a history of a previous admission for trauma, termed by the authors as "trauma recidivism." The incidence of trauma recidivism was addressed by a review of 150 consecutive admissions to a level I Trauma Center. This study identifies this subset of trauma patients, establishes their magnitude, and analyzes mechanisms of injury and hospital courses. The implications for those who care for trauma patients is discussed.
